Application information
Operating voltages
The TSV6390 and TSV6391 can operate from 1.5 to 5.5 V. Their parameters are fully
specified for 1.8, 3.3 and 5 V power supplies. However, the parameters are very stable in the
full V
1.5 V. Additionally, the main specifications are guaranteed in extended temperature ranges
from -40° C to +125° C.
Rail-to-rail input
The TSV6390 and TSV6391 are built with two complementary PMOS and NMOS input
differential pairs. The devices have a rail-to-rail input, and the input common mode range is
extended from V

slightly degraded (as shown in
The devices are guaranteed without phase reversal.
Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: 35 mV maximum above
and below the rail when connected to a 10 kΩ resistive load to V
Shutdown function (TSV6390)
The operational amplifier is enabled when the SHDN pin is pulled high. To disable the
amplifier, the SHDN must be pulled down to V
output is in a high impedance state. The SHDN pin must never be left floating, but tied to
